I have the exact same hangups, and still leaning towards the 7 (primarily because it's the latest and greatest with better technology/support).
My biggest hangup though is the lack of a rear facing camera. I'm a single dad and like taking videos and photos of/with my daughter and letting her watch them at that very moment. I just thought it would be cool to let her do that on the tablet as well instead of having to reach for my phone and switching. I just wanted it to do everything my phone can do, but it's not that big of a deal.
But, I've been convincing myself this...
Nexus 7 16gb
Microsoft Surface Tablet
Samsung Galaxy Note II (if Sprint carries it)
That will do everything I need.
